Answer:
41
Step-by-step explanation:
first you do 21×2 and that's literally it
Step-by-step explanation:
Step 1: Multiply the 2 with the X to get 2X.
Step 2: multiply the 2 with the 4 and get 8
Step 3: your answer is 2X+8
Take the deritiivive

it is zero at pi/4 and it repeats at every pi
minimum at where slope goesfrom negative to positive
so at 5pi/4 and 13pi/4 so at every 2pi interval
evaluate origial at 5pi/4

=

=

or aprox 1.22509
It’s a I think but I’m not sure
Answer:
Step-by-step explanation:
f(x) = x² is an up-opening parabola with vertex (0,0). There is one x-intercept, and that is the vertex.
g(x) = x²-7 is the equivalent to f(x) shifted down 7 units. Since the vertex is below the x-axis and the parabola opens upwards, it intercepts the x-axis at two points.
